If you’re seeking clarity amidst the bubbles of uncertainty, join us in exploring the alluring realm of betta fish care. Dive deep into understanding their oxygen requirements and the significance of air pump for betta fish in their aquatic abode.

Do betta fish need oxygen?

Certainly! Bettas are unique fish that can breathe both in the water and at the surface. While they have the ability to survive in lower oxygen levels, it’s important for their well-being to have sufficient oxygen in their tank water.

Although they can manage in bowls, it’s worth noting that bowls can restrict the availability of oxygen in the water, which is not optimal for their health. To ensure your betta fish thrive, it’s recommended to provide a well-oxygenated environment, such as a properly equipped aquarium.

When Should You Use an Air Pump?

1. When Your Betta Shows Signs of Illness

If your Betta Fish is unwell and receiving medication, introducing an air pump can aid in its quicker recovery. Medication side effects can deplete oxygen levels, which an air pump can counteract.

By boosting oxygen levels and minimizing carbon dioxide, a betta air pump can create a healthier environment for your fish to recuperate.

2. When Your Filter Stops Working

In emergencies like a malfunctioning filter, an air pump can be a temporary solution. Filters uphold water cleanliness and oxygenation.

If a filter breaks unexpectedly, adding an air pump for betta fish can maintain essential oxygen supply until the filter is repaired or replaced.

3. When Your Betta Seems Less Playful

To enhance your Betta’s liveliness and create an engaging environment, consider incorporating an air stone. While Betta Fish can survive without constant water movement, adding an air pump generates oxygenation.

If your Betta appears lethargic, an air pump for betta fish can energize them by enhancing oxygen levels and producing lively bubbles.

Use aquatic plants to provide oxygen

Don’t overlook the benefits of incorporating live aquatic plants in your tank. These plants not only enhance water quality but also enrich the tank’s aesthetics and provide hiding spots for your fish.

Aquatic plants engage in photosynthesis, utilizing CO2 and emitting oxygen into the water. This natural process effectively elevates oxygen levels. Consider adding plants like anubias, hornwort, elodea, or java fern – all simple-to-cultivate options.

Do air pumps stress betta fish?

Yes, they can. Air pumps, primarily used to produce surface movement, can disturb the water’s peace. Bettas typically favor more tranquil waters. Thus, excessive surface agitation from an air pump for betta fish might lead to their discomfort.

How long can betta fish survive without oxygen pump?

Betta fish can survive out of the water for a limited time, as long as their skin remains moist. In optimal conditions, like cool and humid air, they can endure for approximately 2 to 4 hours. However, in hot and dry conditions, this duration significantly decreases to around 30 minutes due to the risk of dehydration.

How do I know if my betta fish needs oxygen?

Signs that your betta fish might be in need of more oxygen include reduced swimming activity and decreased appetite. As oxygen levels decline further, you may observe labored breathing and rapid gill movements. The fish will attempt to extract more oxygen from the water by passing additional water over their gills.


Bettas possess labyrinth organs, allowing them to extract oxygen from air. They don’t demand high oxygen levels for their well-being, but air pumps for betta fish can be beneficial in specific circumstances.

Betta Fish can coexist with a filter, yet an air pump becomes valuable when they’re unwell, in need of stimulation, or during filter malfunctions.

Air pumps play a significant role in elevating water oxygenation and preventing stagnation.

Having reviewed this guide, you now possess a clear understanding of when and how to utilize an air pump for your betta tank, ensuring the optimal conditions for your fish’s comfort and health.

Concluding our dive into betta fish care, we’ve tackled the question, “Do Betta Fish Need Air Pump & Oxygen in Their Tank?” Despite their unique abilities, an oxygen-rich setting remains essential for their health.
